FIRE-PLACE.

SPECIFICATION forming part of Letters Fatent No. 359,868, dated March22, 1887.

Application filed April 3, 1386. Serial No. 197,627. (No model.)

To all whom it may concern:

Be it known that \V6,DOUGLAS P. Lnwis,AunRnwM. JOHNSON, and JOHN W.JOHN, citizens of the United States, and residing in Gin- 5 cinnati,inthe county of Hamilton and State of Ohio, have invented a new and usefulImprovement in Open Fire-Places, of which the following is aspecification.

Our invention relates to heating apparatus;

: and the principal object is to construct an attachment to the ordinarygrate or fireplace for utilizing a large per cent. of the heat whichordinarily passes up the chimney and is wasted.

Figure l is an isometric perspective view of I the principal features ofthis invention and its application. Fig. 2- is a section of theapparatus to show more clearly the circulation of the heated gases.

Similar letters of reference refer to like parts in all the drawings.

Referring to the drawings, the parts A, B, B, and O are hollow castings.The hollow part A forms a hollow lintel, and is usually cost in onepiece with the hollow jambs B B. The hollow part of the lintel A is incommunication with the hollow part of the jambs B B, at the top, asshown by the front of the rigl1t-hand end of the lintel A being brokenaway. The hollow jambs B B are in communication with the hollow base orhearth O, as shown in Fig. 1, by the lower end of jamb B being brokenaway, and by thewletter H in Fig. 2. The hollow base or hearth G, asshown by Fig. 2, communicates with the fine D at I.

At the under side of the hollow lintel A is an opening, J. (Shown inboth Figs. 1 and 2.) This opening is almost as wide as the hollowlintel, and extends from the inside of hol- 0 low jamb B to the insideof hollow jamb B.

E is a grate, which can be of any pattern to give the best results tohold the fuel in condition for combustion. The back and side walls whichinclosc the grate may be either of brick,

cast-iron, or any other material best suited to the purpose.

At the front of the base O is a door, G, in

which is a register, K. The door is opened whenit becomes necessary toclean out any accumulation of ashes or soot in the base.

The register K, when the door G is closed,

can be opened whenever it is necessary to bank the fire, and by thismeans the cold air near the floor will be taken up the chimney and thedraft at the grate checked to the exact degree desired. By this means,also, any carbonic-acid gas which may be evolved from the grate will becarried along with the current of air at the register.

The hollow lintel A, hollow jambsB B, and hollow base G are usually tobe made of castiron about one-quarter of an inch thick, and of a form togive an ornamental appearance.

To understand the Operation of this improvement it must be firstunderstood that the only communication the grate has with the chimney isthrough the long opening J at the under side of the hollow lintel A. Itfollows, therefore, that the upward draft in the due is continuallysupplied by ai r entering the hollow lintel A. lfa tire is built in thegrate, theproducts of combustion will rise by the heat, and the inwardcurrent at the long opening J will carry them into the hollow lintel A,thence right and left to the hollow jambs B B, and

downward through them to the hollow base or hearth O, and thence back tothe rear (see arrows, Fig. 2) and out into the ilue D through thepassage I.

It is readily seen that since there is no direct passage up the chimney,like an ordinary fire-place, the heated products of combustion will, inaddition to radiating the usual amount of heat, also giveout alargcamount of heat to the hollow parts A B B and base O, which in turnradiate it into the room, instead of wasting it up the chimney; also,since there is no direct draft up the chimney, all accumulations of sootfrom the flue will fall back in the rear, near the passage I, Fig. 2,and can be taken out through the removable registerdoor at O.

This apparatus combines the heating qualities of a stove with thecheerful appearance of an open fire-place, and will give a maximum 95degree of heat with a minimum of fuel consumed. On account of the heatedgases of jeoting forwardly of the front walls thereof, r 5

the hollow lintel A, open on its under side;

and the hollowjambs B B, opening at their tops into said lintel and attheir bottoms into said hollow base, said lintel and jambs being adaptedto fit against the lintel and jambs of 20 the fireplace and forma'finishingtherefor.
